CHASSIS-FRAME FO-R AUTOMOBILES.

Application filed May 7, 1918.

tions for the chassis longitudinals whichl shall not only efficiently stiffen the chassis but shall serve certain other useful purposes, as will hereinafter appear, thereby simplifying the construction of the car and reducing the number of supplemental ttings required in the use thereof.

The cross-connections for the chassis longitudinals according to the present .invention comprise a fiat tubular box midway between the ends of the chassis and projectingoutwardly at its ends beyond the chassis longitudinals, and also a luggage-tray of the kind hereinafter described, between the after ends of the longitudinals.

In the accon'lpanying drawings,

Figure l is a side elevation and Fig. 2 a plan ofl a, chassis having crossconnections between the longitudinals such as are above referred to and hereinafter described in detail;

Fig. 3 is a section on the line 3, 3, Fig. 2 of one of the cross-connections which is of box form; and u Fig. 4 is a sideelevation of a car pro vided with my improved construction.

Like reference letters indicate like parts throughout the drawings.

Referring to the drawings, according to the present invention there are combined with the two longitudinals L1 L2 of the chas.

sis and a transverse tie such as T of any convenient form connecting them near their fore ends, a box B forming the middle crossbrace. for the longitudinals and secured to the under side thereof. This box is Wide and shallow'and projects (see/Fig. beyond the longitudinals at each side of the car to form thereva longitudinal step-board SB or step-support. The box is of light sheet. metal and to distribute over the projecting ends of it any load which comes upon the step-portion, there may be laid upon the top of the latter a light stiff ribbed Specification of.

plate P of aluminium or any equivalent load-distrifbnter plate to form a treadplatc.

A tray Tc extends horizontally a'cross between the after ends of the longitudinals L1 L2 with its bottom horizontal and strengthened by a layer of light corrugated plate. CP or an equivalent stitt'ener laid on it and fixed to it, the length of thel corrugations in the plate extending crosswise of the car. The rear edge of the tray terminates, preferably, opposite the standing pivot PV vof the rea-r spring shackle at the extreme after end of the longitudinal. The fore end T1 of the tray is inclined upwardly from the bottom, and the sides and front margin of the tray are flanged at to engage with the aforesaid longitudinals and to support part of the car body, at the after end of which the longitudinals and the tray project, so as to provide a support for luggage.

()ne end of the box cross-brace B above referred to may be provided with a tooldrawer TD (Fig. 3) inserted into it and the other end is adapted to receive a spare tire ST.

The construction of the box is preferably as follows The bottom is a flat light sheet l bent up through ninety degrees at its-forward and after ends 2 and 3 and flanged outwardly at at along the margin of these upturned ends. It is strengthened by angle-iron stiffeners such as 5, 6 preferably arranged in an X form and riveted on to the bottom, or the box may be stamped with convenient corrugations. The top is a fiat plate 7 secured upon the portions iianged outwardly as aforesaid. This may also be strengthened by an approximately square loop 8 of angleiron laid on and riveted to it or `also be made with corrugations.

The said top isdished with a longitudinal inclined channel 9 and the adjacent after end of the box is correspondingly notched at. l0. The shape of the dishing and of the notch is such that on the top of the box the said channel or groove commences at 9a near its forward edge and proceeds aft, gradually becoming wider and `deeper' as it approaches the notch in the afterside of the. box. The groove is shaped thrs in order to afford a suitable clearance space along which the usual connection (not shown in secured upon the drawing) between the gear-box and the rear axle may extend over thetopof the box with the necessary freedom for vertical movement in relation thereto.

T he depression (see 9" Fig. which will be found on the inside of the box as a result of the provision of the groove upon the outside of the top adords a convenient abutment against which the tire ST may be lightly jammed and held by the closing of the door D of the corresponding end of the box or otherwise ligthly pressed into place so that the tire will be lightly held fixed in position in its receptacle, and will not move 'about therein or rattle.

In Fig. 4 I have illustrated the manner in which the horizontal foot-board B may be readily combined with a front mudguard FM rising from its forward end, and a rear mudguard RM havinga straight portion X, a circular portion Y and a downwardly eX- tending portion Z terminating opposite to the stationary pivot PV on the chassis of the after shackle of the rear spring.

Vhat l claim as my invention and to secure by Letters Patent is 1. In an automobile chassis-frame, the combination with two longitudinal members, and a transverse tie connecting the same near their fore ends, 4of a Hat tubular boX constituting a middle`cross-brace which is desire secured directly to the underside of the' middle portions of the longitudinal members and projects laterally beyond the latter at each side thereof to form step-boards, for the purpose specified, substantially as' described.

2. In an automobile chassis-frame, the combination with .two longitudinal members, and a transverse tie connecting the same near their fore ends, of a flat tubular box having forward and after outwardlyflanged ends integral with its bottom, and a flat plate constituting the top of the box the flanges of the said ends, said box constituting a middle cross-brace which is secured directly the middle portions of the longitudinal members and projects laterally beyond the latter at each side thereof to form stepboards, substantially as described.

3. In an automobile chassis-frame, the combination with two longitudinal members, and a transverse tie connecting the same near their fore ends, of a flat tubular box constituting a middle cross-brace which is secured directly to the underside of the middle portions of the longitudinal members and projects laterally beyond the latter at each side thereof to .form step-boards, the top of the box beingprovided with a chanto the underside of' misses nel situated in the central vertical longitudinal plane between the two longitudinal members, which channel is narrower at its forward end and becomes wider and deeper vtoward its rear end adapted to receive a part of the operating mechanism of the automobile and form a partial division of said tubular box, for the purpose specified` substantially as described. y *I A. In an automobile chassis-frame, the combination with two longitudinal menibers, and a transverse tie connecting the same near their fore ends, of a flat tubular box constituting a middle cross-brace which is secured directly to the underside of the middle portions of the longitudinal members and projects laterally beyond the latter at each side thereof to form step-boards, and a sheet-metal luggage-tray having a horizontal :bottom constituting a rearf cross-connection which is secured directly to the after ends of the said longitudinal members, for the purpose specified, substantially as described.

5. ln an automobile chassis-frame, the combination with two longitudinal members, anda transverse tie connecting the same near their fore ends, of a flat tubular box constituting a middle cross-brace which is secured directly to the underside of the middle portions of the longitudinal members and projectsl laterally beyond the latter at each side thereof to form stepboards, a sheet-metal luggage-tray having a horizontal bottom constituting a rear crossconnection which is secured directly to the after ends of the said longitudinal members, and a plate having corrugations directed transversely relatively to thel longitulinal members secured on the bottom of the luggage-tray, for the purpose specified, substantially as described.

6. ln an antom'obile chassis-frame, the combination with two longitudinal members, and a transverse tie connecting the same near their fore ends, of a flat tubular box constituting a middle cross-brace which issecnred directly to the underside of the middle portions of the longitudinal members and projects laterally beyond the latter at each side thereof to form step-boards, and a sheet-metalv luggage-tray having'a horizontal bottom constituting a rear cross-connection, the fore end of the tray slanting upward from the bottom, and the sides and front margin of the tray being ia-nged and secured by the flange to the after ends of the said longitudinal members, for the purpose specified,.substantially as described.

ln testimony whereof l affix my signature.
